Chlorfluazuron, flufenoxuron and XRD-473 were applied to wheat grain as water emulsion at doses of 0.5, 5 and 25 ppm AI. The residual bioactivity and its ability to control infestation of the rice weevil, Sitophilus oryzae (L.) was bioassayed at monthly intervals during 8 months storage period posttreatment. All IGRs at the tested doses produced moderate direct toxicity of 18-56 per cent to parent adult weevils, exposed immediately after treatment, which decreased remarkably to 0-18 per cent for adults exposed to IGRs residues in wheat grain at 3 months posttreatment. Data reveals also that all compounds at 0.5-25 ppm and in particular XRD-473 affected
